BTW when I make the active partition on the SDCard with MiniTools, what size do you recommend? I will be making a backup of the stock ROM from B&N Nook Tablet. So I have a 4GB card right now, so do you think 1000MB should be enough for the Active partition?

Another question is for the TWRP .. do you just copy "twrp_2220_sd.img" renamed as "recovery.img" to the active partition or do you use WinImage to write the twrp_2220_sd.img to the SDCard?

Sorry for the questions, but just want to be absolutely sure that I am doing the correct thing.

Rooting means unlocking full admin control of the tablet. Custom ROMs such CM10 typically come with full admin control (i.e., already "rooted"). Furthermore when installed the custom ROM would replace the stock ROM in whole, hence there is no point in rooting stock ROM if you plan to install CM10 internally.

But in case you'd like to root the stock ROM just to see what it's like to use a rooted NT (I too had done this out of curiosity), I would recommend flashing the update.zip referenced in this post at XDA by liquidzoo as it's more up to date than the rooting package assembled by Albert Wertz.

Also, Albert's SDNT16or8gbV4.7.zip is not an archive file for installation to emmc but rather contains a Rooting SD card image and the disk image writer program to write the image to SD.

These builds are for the Nook Tablet, both 8GB and 16GB, HD is most likely the Developer's initials.

CM10.1 was first released late December hence it's not as mature as CM10.0, but if you want to flash it internally and try it out then you need to use the file cm-10.1-2013xxyy-zz-acclaim-HD.zip (those files with SDC suffix are for installing and running CM on SDcard).

To stick with CM10.0, "cm-10-20121231-NOOKTABLET-acclaim-HD.zip" is the correct, most recent file, right?

Also, is it OK to do the back up to the same SD card (8GB), with just one full (8GB) partition, that has the same files used for the flash? And some posts talk about partition size. Is that only a concern when booting CM from the SD instead of eMMC?

I am still running CM10.0 ("cm-10-20121231-NOOKTABLET-acclaim-HD.zip") internally and am pretty happy with it -- even with its few annoying quirks (charging and storage related).

I have an earlier version of 10.1 installed on SD but has not played with it much: the handful of new features introduced by JellyBean 4.2 (on which CM10.1 is based) aren't compelling for me to leap onto 10.1 at this point. I'll eventually get on 10.1, sooner rather than later if it incorporates fixes for known bugs left unsolved in 10.0 final.

Yes, I too have a single-partition 8GB card which I use exclusively for backup and flashing ROM on emmc. Boot partition sizing is a consideration only in the case of running CM off an SDCard which entails having 3-4 distinct partitions.

I did this, and everything seems to work wonderfully, with one very big exception:

I can't connect to any Wifi networks. It will say Obtaining IP Address for a long time and then try connecting again over and over. I went into the Advanced Wifi settings and found the Wi-fi Region Code set to Europe. I change it to United States, and it keeps going back to Europe. Any way to fix this?

If it says "Obtaining IP Address" then the radio network has already connected which means that the region code is not causing the problem? The most common cause of problems related to "Obtaining IP Address" are password errors, because password difficulty will cause the data decryption to fail and make obtaining an IP address impossible.

It's definitely not a password issue. I have 2 home Wifi networks, both with the same password, and a half dozen other devices are all able to connect without issue, as was this particular NT with CM7. It's not a hard password, and I've checked that it is correct around 100 times. Also, I had never heard of the Wifi Region Code thing, but I find it more than a little suspicious that while it won't work, it also happens to be set to Europe and will not change to United States, no matter what I do. Any thoughts on a way around that? By the way, I have flashed CM10 to the device twice thinking maybe there was some kind of error setting it up. The result was exactly the same. Everything else seems to work flawlessly. Just not the Wifi. Which puts a huge damper on the whole thing. Thoughts?

I did not say that you had the wrong password, but that you had a password issue since the radio was apparently working fine. The very last step in the WiFi connection protocol is "Obtaining IP Address" from the router. For that step to be reach the radio must establish a connection on an agreed upon channel, then process the access password to enable data decryption, and once data can be decrypted the mobile requests an IP address to join the network. If the decryption key is not correct, the request for a IP address will not be decrypted by the router and the router will sit there patiently waiting for the final step from the mobile, which cannot happen because the data is not correctly decrypted. One easy way to check that is to TEMPORARILY turn off encryption so that data is not encrypted between the mobile and the router. If that works then you have significantly narrowed down the problem.

The fact that you cannot switch does point to a possible software defect in your Android WiFi system. The Europe code "thing" mainly adds two extra WiFi channels since the USA only has 11 channels and the rest of the world has 13. The 11 USA channels are also in the Europe channels so your Nook should be able to connect to your USA router.Reference

I have set up CM10 internally on two Nook Tablets (no SD kludge), so I am sure that the CM10 version that I downloaded does not have the problem that you are having. I know that is not much consolation, but if you are using a "nightly" maybe try downloading a stable version?
